+
+### Properly hijack require
+
+This library allows to add custom require hooks, which do not interfere with other require hooks.
+
+This library only works with commonJS.

+
+## Why?
+
+Two reasons:
+1. Babel and istanbul were breaking each other.
+2. Everyone seemed to re-invent the wheel on this, and everyone wanted a solution that was DRY, simple, easy to use,
+and made everything Just Work™, while allowing multiple require hooks, in a fashion similar to calling `super`.
+
+For some context, see [the Babel issue thread][] which started this all, then [the nyc issue thread][], where
+discussion was moved (as we began to discuss just using the code nyc had developed), and finally to [#1][issue-1]
+where discussion was finally moved.

+
+## Installation
+
+    npm install --save pirates
+
+## Usage
+
+Using pirates is really easy:
+```javascript
+// my-module/register.js
+const addHook = require('pirates').addHook;
+// Or if you use ES modules
+// import { addHook } from 'pirates';
+
+function matcher(filename) {
+  // Here, you can inspect the filename to determine if it should be hooked or
+  // not. Just return a truthy/falsey. Files in node_modules are automatically ignored,
+  // unless otherwise specified in options (see below).
+
+  // TODO: Implement your logic here
+  return true;
+}
+
+const revert = addHook(
+  (code, filename) => code.replace('@@foo', 'console.log(\'foo\');'),
+  { exts: ['.js'], matcher }
+);
+
+// And later, if you want to un-hook require, you can just do:
+revert();
+```
+
+## API
+
+### pirates.addHook(hook, [opts={ [matcher: true], [exts: ['.js']], [ignoreNodeModules: true] }]);
+Add a require hook. `hook` must be a function that takes `(code, filename)`, and returns the modified code. `opts` is
+an optional options object. Available options are: `matcher`, which is a function that accepts a filename, and
+returns a truthy value if the file should be hooked (defaults to a function that always returns true), falsey if
+otherwise; `exts`, which is an array of extensions to hook, they should begin with `.` (defaults to `['.js']`);
+`ignoreNodeModules`, if true, any file in a `node_modules` folder wont be hooked (the matcher also wont be called),
+if false, then the matcher will be called for any files in `node_modules` (defaults to true).

+(And you should! It works best if everyone uses it. Then we can have a happy world full of happy require hooks!), please
